DBAFT-DEFLEOIOR FOR VENTILATlING-SCREENS OF SLEEPING-BERTHS.

Application filed July 19, 1917.

To all whom it may concern:

Be it known that 1, WILLIAM Mnnonn SPARKMAN, of the city of Toronto, in the county of York, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Draft-Deflectors for VentilatingScreens of Sleeping-Berths, of which the following is the specification.

My invention relates to improvements in draft deflectors for ventilating screens of sleeping berths and the object of the invention is to devise means for deflecting the draft caused by the rush of air passing over the outer face of a car from entering through the screen into the berth upon the occupant and it consists essentially of the following arrangement and construction of parts as hereinafter more particularly explained.

Figure 1, is a perspective view of the exterior portion of a Pullman car showing a portion of the window showing the ventilating screen and my device extending from the screen.

Fig. 2, is an enlarged perspective detail of my deflector connected to a portion of the screen.

Fig. 3, is a sectional plan view Fig. 2.

Fig. 4, is a sectional plan view showing my deflector in the closed position.

Fig. 5, is a vertical section on line wy through %II the drawings like letters of reference indicate corresponding parts in the various figures.

1 indicates a car window in which is placed the usual screen 2 formed of metal mesh. Secured to the screen 2 and extending at right angles therefrom is a deflecting supporting member 3 having a rectangular orifice 4 therein.

5 and 6 indicate members hingedly connected to the member 3 at the upper and lower end of the orifice 4. 6 indicates a member hingedly connected at the inner edge of the orifice 4 to the member 3, such member being provided with a hinged extension 7. 8 and 9 indicate grooves formed in the members 5 and 6 into which the upper and lower edges of the members 6 and 7 extend. 10 and 11 indicate hook and eye connections by which the members 5 and 6 are connected to the member 7 so that the upper topics at this patent may be obtained for Specification of Letters Patent.

and lower edges of the members 6 and 7 are held within the grooves 8 and 9 thereby holding the deflecting structure rigidly together.

As will be readily seen on referring to Fig. 1 when the train travels in the direction of arrow the rush of air passing along the outer face of the car on a level with the screen 2 passes through the opening 4 and is caught by the angularly set deflecting members 6 and 7 and directed outward at right angles to the car thereby preventing such air passing through the screen to form a draft upon the occupant of the berth, also incidentally preventing fine dust or dirt in the form of cinders passing through the screen into the interior of the berth.

When it is desired to store my screens all that it is necessary to do is to loosen the hook members 10 and 11 and collapse the structure, this being done by first slightly raising the members 5 and 6 so as to free the members 6 and 7 from the grooves 8 and 9 swinging the members 6 and 7 slightly outward, then swinging the members 5 and 6 inward into the position shown in Fig. 5, then swinging the member 7 inward against the member 6 and then swinging the member 6 inward toward the members 5 and ,6. By this means the deflector and screens may be packed away very compactly so as to take up a minimum amount of storage room.

vVhat I claim as my invention is.

In a device of the class described, a main support having an orifice therein, a collapsible cowl structure extending over such orifice and comprising upper and lower members hingedly connected to the supporting structure at the upper and lower end of the orifice, an angularly set deflecting member extending from the inner edge of the orifice between the upper and lower members, an extension member hingedly connected to the outer edge of the angularly set member, means for detachably connecting the ends of the extension member to the upper and lower hinged members, said upper and lower members being grooved for the reception of the horizontal edges of the deflecting and extension members.
